Question

请求接口http://ip:port/actuator/metrics/hikaricp.connections.usage

返回：

{
    "name": "hikaricp.connections.usage",
    "description": "Connection usage time",
    "baseUnit": "seconds",
    "measurements": [{
            "statistic": "COUNT",
            "value": 70291
        },
        {
            "statistic": "TOTAL_TIME",
            "value": 562.648
        },
        {
            "statistic": "MAX",
            "value": 0.013
        }
    ],
    "availableTags": [{
        "tag": "pool",
        "values": [
            "DatebookHikariCP1",
            "DatebookHikariCP2"
        ]
    }]
}

请问以上的COUNT,TOTAL_TIME,MAX是什么意思？

COUNT,TOTAL_TIME我猜测为连接总使用次数、连接总使用时间。

但MAX猜不出是啥玩意.
